Product Detail

Challenges Of The Multilayer PCB

Multilayer PCB designs are more expensive than other types. There are some usability issues. Because of its complexity, the production time is quite long. Professional designer who needs to manufacture multilayer PCB.

Main Features Of Multilayer PCB

1. Used with integrated circuit, it is conducive to miniaturization and weight reduction of the whole machine;

2. Short wiring, straight wiring, high wiring density;

3. Because the shielding layer is added, the signal distortion of the circuit can be reduced;

4. The grounding heat dissipation layer is introduced to reduce local overheating and improve the stability of the whole machine. At present, most of the more complex circuit systems adopt the structure of multilayer PCB.

A Variety Of PCB Processes
